A leading steel manufacturer faced the dual challenge of severe scaling in its circulating cooling water system and the resulting equipment corrosion. Heat-exchanger efficiency declined, the risk of localized pipe corrosion and perforation increased, system pressure loss rose, and energy consumption grew, creating an urgent need for professional support to ensure stable operation.

PRIO provided integrated operation and maintenance services combining technology, management, and execution, including:

Refined water-quality management through routine monitoring and precise laboratory analysis, with strict control of cycles of concentration, saturation indices (LSI/RSI), and key ion concentrations.

Data-model-based calculation and automatic adjustment of the dosage and dosing cycles for corrosion inhibitors, scale inhibitors, dispersants, and non-oxidizing or oxidizing biocides, ensuring efficient, low-consumption, and precise chemical treatment.

Operational optimization, water conservation, and emissions reduction through optimized blowdown strategies and automatic control systems. While maintaining stable water quality and compliant corrosion and scaling control, the cycles of concentration were increased.
